Application led :February 1, 1915. Serial No. 5,550.

Be it known that I WILLIAM STEINBERG,

` a subject of the Czar of Russia, and a resident of Jamaica, county of Queens, and Statev of New York, have invented a certain new and useful Improvement 1n Compound Resilient Tires, of which the following is a" full, clear, and exact specification.

' This invention relates to a class of devices adapted to be used in conjunction with vehicles.

My invention has for its object primarily to provide a form of tire designed to be utilized on the wheels of automobiles and likeA vehicles whereby a cushion-like action or resiliency will be attained as well as serving f to obviate the tendency of being punctured as is incident to the pneumatic tires ordinarily used, and which is adapted to be made so as to be efficiently employed on both y passenger automobiles and auto-trucks withvide on the transverse part of the annular semi-hexagonal resilient member aferrule, or grooved concentric supporting plate `for permitting the resilient member Vtojbe detachably fastened on the wheel of the vehicle, to provide means for fastening the` resilient member against movement to the ferrule; to provide between the free edges of the flanges of the resilient member an any nular rigid bridging member, or plate for holding the flanges in uniform spaced relation; to provide on the bridging member an annular resilient or Vyielding tread member; and to provide clamps, or annular retaining strips for detachably holding the tread member on the bridging member, and to detachably hold the bridging member'to the flanges provide a tire` of simple and efficient` construction, and which may be made so as to e' may said invention being more fully described hereinafter, and then pointed out in the claim at .the end of the description. j

ln the drawing, Figure 1 is a side View ofa vehicle wheel partly in section showing `one form of resilient tire embodyingmy invention applied thereto, and

Fig. 2 is an enlarged sectional view taken through the tire and through the rim of the wheel.

The compound resilient tire has an annular grooved, or fianged member 10 which be made of rubber, or other resilient material, and this resilient annular member is preferably substantially semi-hexagonal in shape, as viewed transversely, to permit an air-chamber, or pneumatic cushion, as 11, to be provided as well as forming the transverse part, or base 12 thereof with a flat inner side and forming outwardly diverging fianges land 14 the edges of which terminate withcircular-shaped headings 15 and V16, respectively; `The annular semi-hexagonal resilient member 10 is made of a size so that the transverse part,`or base l2 is somewhat wider than the felly 17 of the wheel 18 of an automobile, or like vehicle, and the flanges 13 and 14 are formed to eX- tend a suitable distance beyond the periphery of the wheel. In a passage lengthwise through the annular resilient member 10 at the juncture of its fiange 13 with Vits base 12 is disposed an annular'metal rod 19, and in a passage lengthwise through the resilient member 10 at the juncture of its flange 14 `with its base is a second annular metal rod 20. In apassage lengthwise through the beading 15of the flange 13 is a third annular metal rod 21, and in a passage lengthwise through the beading 16 of the flange ll is a fourth annular metal rod 22. The rods 19, 20, 21, 22 may be cut, and the resilient member may likewise be cut for permitting the rods to be passed through the passages of the resilient member after which the ends of the rods may be welded or soldered and the ends of the `resilient member may be cemented together, or these parts maybe combined by alsuitable process of molding. These rods are tightly held in the passages of the resilient member' to limit the tendency of :the .member to expand or contact circumferentially when in use, and .in order to reinforce the resilient member in its base 12 and in the beading ofthe ilangesnl?) and 14 may be embedded layers7 as 23, ot canvas, or other suitableniaterial.

To perinit the annular semi-hexagonal resilient meinber l0 to be detacliably fastened on the `Wheel of `a gvehicle,`a errule, or

grooved concentric supporting plate tpreferably oi2 metal is provided. The concentric supportingplate 2li ,has a transverse part 25, and 'the lengthwise edges ,of this plate arebent outwardly to torni two curveddivergingflanges andQ?, the space between which provides an annular groovein `which rests thebase 120i the resilient member 10.

Serving as means Ato -lasten the resilient member l() against" movement to .the snpporting plateQL, on the outer "perpheryot `the transyerse.partei this :member is arrangeda .curvedconcentric strip 28 having a number oi spaced bosses 29 projecting therefrom. rlllirough the strip and Vthrough each of the bosses 29 as well as through the resilient member 10,`and`also through the transverse part of theconcentric supportingplate 2li` are registeredholesin each set of which is passeda bolt 30 having a head 31 abuttingagainst the inner `side yof the transverse part 25 of the supporting plate `24, and on the opposite threaded end of each ot these bolts is a tightening nut'` 32 which is screwed into engagement with the boss of lits bolt, thusdastening theannular resilient member 10to the1 grooved concen- 4' tric .supporting plate `211.

.ber l0, and projectingi'rom the edges ofthe ,3G4 ofthel br' A l y shown, and in these grooves are 'respectively disposed .the beading 15L andl of thelanges .ofthe resilientA member 10. ,In this manner F or the purpose of lioldingthe flanges 13 Vand le ot the annular semi-hexagonal `resilient `member `10 in unitorm spacedfrelation as Well as closing the spacebetween the 4free edges oi thesewllanges `to provide the airfchamber, or pneumatic cushion V1l, between `tliebeading lrand 16 oit the fianges is removably disposed Van annular rigid bridging-member, or plate 33 preferably ot' metal. `The bridge-plate `33 has a transyerseportion 3l disposed crosswise with respect to thejlanges `of the resilientinemtransverse portion of the bridge-plate inwardly between the tlangeswof the resilient `member are two annularilanges 35 and 36 which are spacedV asulilcient distance apart z so thaty the flanges 13a`nd 14 of the resilient member abut V tliereagainst, for ,being uiiitornilyspaced apart. `The cuter surfaces at tlieiree edge portions of the lilanges 35 and plate 33 are grooved, as

' the transyerse portionBet of the bridgefplate 33 and also part of tlie'iianges-B and 36 extend some distance beyond the peripheral .planegof ythe resilient member7 and.; this bridge-plate further serve'sto close the air nular groove of the resilient member to pro- `vide the `air-chamber, or pneumatic cushion 11, thereby allowing the use of an inner .pneumatic tube to be dispensed with.

similar material is preferably embedded in the part adjacentto its inner side during the molding of the niefrnbei". so .as `to strengthen it, and on the curved tread Surtace of themeniber maybe lornieda `suitable number oi teats,`or Vknobs iilto preif'ent the wheel.fromshielding.l

In Aorder to detachably fhold the tread member 37 on the .bridge-plate 33 and for also removably-liolding the bridge-*plate tothebeading of the iiangcs 13and 14 of the annular resilient menlber 10,1 provide two clamps7 or concentric retaining rings, as e2 p and d3, both oi.i which" are similarly formed.

`Vl7hen the resilient tire is applied to the wheel of an automobile the grooved concentric supporting plate 24 is disposed on the usual metal rim, as 50, of the telly 17 of the Wheel so that the heads 31 `of the bolts will rest on this rim, and the tire is then removably secured on the wheel by means of the usual forms of wedge-clamps, as 51, as ordinarily used for this purpose. rlhu's a simple and etlicient form of compound resilient tire adapted to combine great strength and durability is provided for use on the wheels of automobiles and like vehicles to produce the required resiliency without requiring the employment of a pneumatic inner tube as well as serving to obviate the tendency of the tire to being punctured.

In the foregoing description, I have em bodied the preferred form of my invention, but I do not wish to be understood as limiting myself thereto, as I am aware that modications may be made therein without departing from the principle or sacrificing any of the advantages of this invention, therefore I reserve to myseltthe right to make such changes as fairly fall within the scope of the appended claim.

Having thus described my invention, I claim as new and desire to secure by Letters Patent A tire comprising an annular flexible and resilient member having a reinforced continuous transverse portion, two continuous outwardly extending and diverging side flanges, each flange having a reinforced annular bead at the tree edge thereof, a flat annular bridge member of rigid material spanning the space between the side flanges, said bridge member having inwardly eX- tending continuous side iianges with grooves in the outer side faces thereof receiving the beads of the resilient member flanges, an annular tread member mounted on the bridge member and having curved sides, annular rings arranged at each side of the bridge member, said rings each having an inner continuous ila-nge substantially arcshaped in crosssection engaging the bead of one of the resilient member ianges and a curved outer continuous flange engaging a curved side of the tread member, and means carried by said rings between their flanges and engaging said bridge member for drawing said rings toward said bridge member to clamp said beads of the resilient member flanges in the grooves of the bridge member flanges and to secure the tread member on said bridge member.

This specication signed and witnessed this thirtieth day of January, A. D. 1914.
